What is a .AFF4 file?
AFF4 is the modern Advanced Forensic Format for evidence disk images.
- Did you know
- AFF4 modernised forensic imaging to handle today’s huge drives.
- AFF4 was published in 2009 by Cohen, Garfinkel and Schatz, rebuilding the Advanced Forensic Format on top of the ordinary ZIP format.
- Unlike its predecessor it can hold several data views in one archive and link between archives, easing selective and hash-based imaging.
- What Analyser reads
- Identify and read more security and forensics files: OpenPGP messages/keys/signatures (.pgp/.gpg/.sig - armor type, packet walk, key algorithm and user ID, secret-key warning), YARA rules, Snort/Suricata IDS rules, STIX/OpenIOC threat intel, Fiddler captures (.saz), 1Password exports (.1pux), Apple Keychain, KeePass 1.x (.kdb), Microsoft keys (.pvk) and AFF/AFF4 forensic images.
- Depth of analysis
- .AFF4 is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .AFF4 file
- Drag a .AFF4 file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
